oi ccieom it may concern it known that 1, JAMES H. Konxs,

o o of the United States, and a resident oi. oi, {)klohonm, have invented a cerium new I tions, through which. the cable extends, and

' barrel section.

in which a swivel member or collar adopted to play, said collar being connected to the lower end of ihe cable, the construction hein such that the pollen or swivel member will not bind against any oi the ports of the device.

A furiher object of the invention is to provide a device of the class described which will be extremely simple, durable, cllicicnc in operation, and inexpensive to monui octore.

With these and other objects in view which willbccome. apparent as the description proceeds, the invention resides in the construction, combination, and arrangement of parts hereinafter more fully described and cioin'icd, and illustrated in the accompanying drawing in which like characters oi reference indicate like parts throughout the several figures, of wh1ch- Figure 1 represents a view in elevation of o swivel joint constructed according to In; invention. Fig. 2 represents a vertical longitudinal sectional. view when there through. Fig. 8 repcsents a view similar to Fig. 1, showing the position of the parts after ihe spring has been removed. Fig. 4;

represents a View in section taken horizontally on the plane indicated by the line H of 2. i

Referring more particularly to the drawing, 5 indicates the upper and c the lower Each is provided with a squared portion *7 for the reception a wrench or other tool to be used in connecting and disconnecting the sections. The upper section. has a reduced, threaded, conical lower end 8 which is adapted. to he turned into the internally threaded comically bored upper end 9 of the lower section 6. Below the conicol portion 8, said upper section exicmls 10 into the bore 11 provided longiimliholly of the lower section' The sci-lion (3 adjacent the lower end of the bore is provided wiih openings or perioroiions 1:2 drainage purposes. The extension i0 is or Videcl with 21- possoge or duct 13 which establishes communication between the here llprovided in section 5, and the bore ll in the lower section 6. This bore 14 is of less dinn1- eter than the bore 11 and through the former extends the cable 15. At its lower cncl. this cable depends within loci-c ll and passes ihroujgh a collar or swivel member 1 3 of annular formation \VlliCl. rrongcd within, the bore 11. This collar or swivel member is of a. diameter somewhat less than the (liilllieter of the bore so as to be capable of really sliding and rotary moveincnc therein. The lower end of cable 15 is bobbitted wiihin the collar 16 as at 17. Disposed upon the cable 15 between the collar 16 and the annular shoulder 18 provided at the lower end of the exiension 10, a coiled spring 19'.

The spring 19 is used as a cushioning (levice while spudding in and during the first.

dicaicd in Fig. 3. the swivel member or collor 16 rests against the shoulder 18 provided at the lower end of the extension 10. Yihen in this position, the collar or swivel member may readily rotate Without hindrance within the lower section. The lower end of section 6 is provided as'indicated at 20, wi h a. threaded conical socket into which may be turned the upper end of a drilling tool.

When the spring is removed the swivel melnher or collar rests directly against the shouldoc 18 when the device is in operation.

It often happens that while the tool is be ing pulled, fine sand settles around the cable 15, when the block 16 is tight up against the lower end of the projection 10. The sand soon becomes packed in around the cable and unless constant drainage is provided, the

tool will become stuck will not eflectivcly operate. The passage 13 provided in BEST AVAILABLE COP the extension has been found to etl'ectnally eliminate this trouble and to afford a constant drainage around the cable, so that even after the tool has been idle. for a long time, the line sand and silt will not have become packed around the cable.

()ne of the peculiar advantages accruing to my device is that the extension 10. as well as the upper end of the collar or swivel member 16. may be case-lnirdened it so desired. while in many other devices of this nature. the shoulder for receiving the strain is so arranged with respect to the section on which it is formed. that it cannot be casehardcned. and hence wears out in a cone parativetv short time. Furthermore. in this device the uniform diameter ol' the barrel member ti prevents wedging ol' the collar w thin the same. and the load or strain is received on the square shoulder in and on the upper end of the collar lb so that the device may revolve upon the collar as a pivot.

Although I havedescribed the preferred embmliment of my invention. l may desire to make such tlHlll ItS in the construction. combination. and arrangement of parts thereof. as do not depart from thc pirit of the invention and the scope of the appended claims.

I claim I l. A device of the class described. comprising an upper and a lower section threadedly ronnected tt'igether. and provided with 'alining bores. the bore in the lower section being of a larger diameter than the bore in the upper section, an extension carried by the upper section and arranged within the bore in the lower section. said extension being provided with a pas ageway communieating with the bores in the sections. and a cable extending through the upper section and into the, lower section and being provided with a collar arranged within the lower section adapted to engage and swivel against the said extension, said (able being babbitted within the collar.

A. device of the class described cone prising a pair of detachablv connected sections, said se tions being provi-iled with alining bores', an extension formed on one of the sections and extending within-the connected together, an extension formed on i one of the sections and extending within the other and provided with a passage connecting the interiors of the sections, and a llexiblo element extending into the. sections and being provided with a swivel member adapted to engage against said extension.

4. A device of the class described, includ ing an uppe' and a lower section provided with alining bores, the bore in the lower section being larger than the bore in the upper section. said upper section being provided with a tapered externally threaded portion screwed into an internally threaded tapered socket in the lower section and having a tempered extension projecting into the bore of the lower section, a cable extending through the upper section into the lower section, and a collar carried by the cable within the lower section and adapted toengage against said extension.

5. A. device of the class described including an upper and a lower section, said sections being provided withalining bores, an extension formed on one of the sections at tending within the other and provided with JAMES H. Kin-ins.
